【Abstract】 To resolve the difficulty in the Fixed Priority Scheduling design of CAN, a effective method name FPSD is proposed. First, the worst case response time is got after introducing the message model and relative definitions, and the schedulable theorem is presented, on the basis of which a series of common steps named are presented to implement the FPS. At last, by taking electric vehicle as an example, the validity of the schedulable theorem and the FPSD is proven.更多还原
